I wonder if I could turn my downstairs den into a dual couch stadium seating area with a wall fan, remove the ceiling fan and add a retractable projector and retractable screen.

This is the idea with the fan, but this one specifically is not sold in the USA.

Retractable screens are a dime a dozen. It seems the big question is if I want it to be manual or powered.
